Description

TECHNICAL FIELD The present application relates to a water treatment device, and more particularly to a water treatment device for controlling water-bloom, water-bloom toxins, and water-bloom off-flavours in reservoirs, lakes or rivers.

Currently, eutrophication of water areas is an environmental problem that seriously affects water quality, and may cause water pollution and adverse effects on the ecological environment. Among them, algal bloom by blue-green algae is one of the important features of water eutrophication. Blue-green algae, also called cyanobacteria, can produce a range of highly toxic natural toxins (cyanotoxins) and off-flavor tastants that endanger human health. When large amounts of blue-green algae grow in reservoirs, lakes, rivers, etc. and form water flowers, they cause great harm to humans.

Conventional techniques for removing algal blooms and algae-producing substances are mainly divided into physical treatment techniques and chemical treatment techniques. Chemical algal bloom removal techniques are primarily carried out by dissolving chemicals in water to interact with algal blooms.

When removing blue-green algae by the above-mentioned conventional techniques, the cell walls of blue-green algae are easily destroyed, causing the outflow of toxins (e.g., microcystin) in the cells of the blue-green algae, which not only causes secondary pollution in water areas, but also causes other problems. It also causes mortality of aquatic animals.

It should be noted that many algae use carbon dioxide ( _CO2 ) as a carbon source for photosynthesis. Besides carbon dioxide, blue-green algae can also use bicarbonate ions (HCO ³⁻ ). When algal blooms overgrow on the surface of reservoirs, lakes or rivers, the pH rises and carbon dioxide becomes bicarbonate ions or carbonate ions (CO ₃ ^2- ), and algae other than algal blooms use carbon dioxide as a carbon nutrient. Since it cannot be used, the growth of algae other than blue-green algae is hindered. Also, since the growth of algae competing with algae is inhibited, only algal blooms grow predominantly.

上記式１において、左側は、酸性環境であり、右側は、アルカリ性環境である。 Equation 1 below shows the reaction of carbon dioxide in water.

In Equation 1 above, the left side is an acidic environment and the right side is an alkaline environment.

By shifting the above equation 1 to the left by lowering the pH value with acidic ionized water and increasing the ratio of carbon dioxide gas, the growth of green algae, diatoms, and other photosynthetic algae that compete with blue-green algae is promoted. It is possible to prevent the preferential growth of blue-green algae.

Furthermore, if the deoxygenation of the water bottom layer, which causes the formation of algae, can be improved, it will be possible to suppress the growth of algal blooms.

As an example, the raw water introduction part 20 may be arranged below the electrolysis chamber 10 . At this time, the raw water can flow vertically in the electrolysis chamber 10 and can easily flow between the cathode and the anode, so that the electrolyte contained in the raw water can be efficiently electrolyzed. Thereby, acidic electrolyzed water and alkaline electrolyzed water can be obtained from raw water.

The user can use the alkaline electrolyzed water discharge unit 30 to discharge the alkaline electrolyzed water to the lower water area below the surface water area, so that the pH value in the bottom area of the reservoir, lake, river, etc. is easily eluted. neutralization, which can raise the pH value to near neutrality, such as 6-7, and can provide cations that immobilize phosphate, thus inhibiting the elution of phosphate, and microcystis spp. can prevent the growth of planktonic organisms to achieve the purpose of water purification.

One end of the acidic electrolyzed water discharge section 40 is connected to the anode chamber 120, and the other end is connected to a drainage device such as a conduit. The user can use the acidic electrolyzed water discharge unit 40 to discharge the acidic electrolyzed water to the surface layer of a reservoir, lake, river, or the like where algal blooms easily grow, thereby killing algal blooms. In addition, when the above formula 1 is shifted to the left by lowering the pH value with acidic electrolyzed water to increase the ratio of carbon dioxide gas, the growth of green algae, diatoms, and other photosynthetic algae, which are algae competing with blue-green algae, is promoted. It is possible to prevent the preferential proliferation of algae, and also to prevent the production of algal bloom toxins and algae offensive tastants.

In this embodiment, both the cathode 111 and the anode 121 are formed in a hollow columnar shape, and the cross-sectional shape thereof is circular, elliptical or polygonal, preferably the polygon is circular or regular polygonal. .

In the structure of the water treatment apparatus according to the second embodiment, the description of the same structure as the structure of the water treatment apparatus according to the first embodiment will be omitted.

FIG. 3 is a structural schematic diagram of a water treatment device according to a second embodiment of the present application. The difference between the water treatment apparatus according to the second embodiment and the water treatment apparatus according to the first embodiment is that a cathode water guide plate 112 and an anode water guide plate 122 can be further included.

As shown in FIG. 3 , the cathode water guide plate 112 is arranged in the cathode chamber 110 and formed to surround the hollow columnar cathode 111 , and the anode water guide plate 122 is arranged in the anode chamber 120 and formed to surround the hollow columnar anode 121 . is formed to surround the

In the cathode chamber 110 , the liquid can be circulated up and down along the cathode water guide plate 112 , specifically, the liquid is guided from the bottom to the top within the cathode water guide plate 112 and led to the top of the cathode water guide plate 112 . After that, it flows from top to bottom outside the cathode water guide plate 112 . Due to such circulation, more electrolyte flows between the cathode 111 and the anode 121, so that the electrolyte can be more fully decomposed. In addition, since the cathode water guide plate 112 is arranged outside the cathode 111 and the liquid in the cathode water guide plate 112 flows from bottom to top, the hydrogen gas generated near the cathode 111 can be efficiently discharged above the cathode chamber 110. and it is easier to efficiently recover the hydrogen gas produced in the cathode chamber 110 .

Similarly, in the anode chamber 120 , the liquid can circulate up and down along the anode water guide plate 122 . After being guided upward, it flows from top to bottom outside the anode water guide plate 122 . Due to such circulation, more electrolyte flows between the cathode 111 and the anode 121, so that the electrolyte can be more fully decomposed. In addition, since the anode water guide plate 122 is arranged outside the anode 121 and the liquid in the anode water guide plate 122 flows from bottom to top, the oxygen gas generated near the anode 121 can be efficiently discharged above the anode chamber 120. and it is easier to efficiently recover the oxygen gas produced in the anode chamber 120 .

The cross-sectional shapes of the cathode water guide plate 112 and the anode water guide plate 122 may be arbitrary shapes, and may be the same or different. Preferably, the cross-sectional shape of the cathode water guide plate 112 matches the cross-sectional shape of the cathode 111 , and the cross-sectional shape of the anode water guide plate 122 matches the cross-sectional shape of the anode 112 . FIG. 4 shows an example in which the cross-sectional shapes of the cathode water guide plate 112 and the anode water guide plate 122 match the cross-sectional shapes of the cathode 111 and the anode 112, respectively.

The heights of the cathode water guide plate 112 and the anode water guide plate 122 may be the same or different. The heights of the cathode water guide plate 112 and the cathode 111 may be the same or different, but preferably the heights of the cathode water guide plate 112 and the cathode 111 are substantially the same. The heights of the anode water guide plate 122 and the anode 121 may be the same or different, but preferably the heights of the anode water guide plate 122 and the anode 121 are substantially the same.

Preferably, the cathode water guide plate 112 matches the cathode 111 in shape, and the anode water guide plate 122 matches the anode 121 in shape. With such a structure, the liquid in the cathode water guide plate 112 including the liquid in the cathode 111 can be better circulated, and the liquid in the anode water guide plate 122 including the liquid in the anode 121 can be better circulated. As a result, the electrolyte can be decomposed more efficiently, and the generated gas can be caused to flow above the cathode chamber 110 and the anode chamber 120, respectively.

[Third embodiment]
Next, a third embodiment of the present application will be described with reference to FIG. In the structure of the water treatment apparatus according to the third embodiment, the description of the same structure as that of the water treatment apparatus according to the second embodiment will be omitted.

FIG. 5 is a structural schematic diagram of a water treatment device according to a third embodiment of the present application. The difference between the water treatment apparatus according to the third embodiment and the water treatment apparatus according to the second embodiment is that the cathode gas-liquid separation plate 113 and the anode gas-liquid separation plate 123 can be further included.

As shown in FIG. 5, the cathode gas-liquid separation plate 113 is positioned between the upper end of the cathode 111 in the cathode chamber 110 and the cathode exhaust port 50 to block the gas-liquid flow to the cathode exhaust port 50 and prevent gas-liquid flow. It can be separated into liquid and gas. The anode gas-liquid separation plate 123 is located between the upper end of the anode 121 and the anode exhaust port 60 in the anode chamber 120 to block the gas-liquid flowing to the anode exhaust port 60 and separate the gas-liquid into liquid and gas. can be done.

In the present embodiment, the shapes of the cathode gas-liquid separation plate 113 and the anode gas-liquid separation plate 123 are not particularly limited, and may be of any shape. The anode gas-liquid separation plate 123 is located between the upper end of the anode water guide plate 122 and the cathode exhaust port 50 and its vertical projection covers the vertical projection range of the cathode water guide plate 112 . It is located between the exhaust port 60 and formed so that its vertical projection covers the vertical projection range of the anode water guide plate 122 .

In the cathode chamber 110, the liquid in the cathode water guide plate 112, including the liquid in the cathode 111, flows along the cathode water guide plate 112 from bottom to top, is advected and diffused by the cathode gas-liquid separation plate 113, and flows to the cathode. It flows from top to bottom along the wall of the chamber 110, which allows better circulation. On the one hand, such a circular flow leads more electrolyte between the cathode 111 and the anode 121, so decomposition produces more alkaline electrolyzed water, which can be used in bottom areas such as reservoirs, lakes or rivers. It neutralizes the low pH value at which phosphate ions are easily eluted, thereby raising the pH value to near neutrality, suppressing the elution of phosphate, and preventing the elution of planktonic organisms of the genus Microcystis (e.g. blue-green algae). can be prevented from growing to achieve the purpose of water purification. On the other hand, due to such circulation, the hydrogen gas produced near the cathode 111 is better guided near the cathode gas-liquid separator 113, and along the wall of the cathode gas-liquid separator 113, the cathode exhaust port 50 , and discharged to the outside through the cathode exhaust port 50, and can be recovered and used as fuel for a fuel cell or the like.

Similarly, in the anode chamber 120, the liquid in the anode water guide plate 122, including the liquid in the anode 121, flows from bottom to top along the anode water guide plate 122 and is diffused around by the anode gas-liquid separation plate 123, It flows from top to bottom along the wall of the anode chamber 120, which allows better circulation. On the one hand, such circulation leads more electrolyte between the cathode 111 and the anode 121, so decomposition produces more acidic electrolyzed water to kill algal blooms, and acid electrolysis Since the ratio of carbon dioxide gas can be increased by lowering the pH value of water by water, the growth of green algae, diatoms and other photosynthetic algae, which are competing algae of blue-green algae, can be promoted, and the preferential growth of blue-green algae can be promoted. In addition, it is possible to prevent the production of blue-green algae toxin and blue-green algae offensive tastants. On the other hand, due to such circular flow, the oxygen gas produced near the anode 121 is better guided near the anode gas-liquid separator 123, and along the wall of the anode gas-liquid separator 123, the anode exhaust port 60 , and is discharged to the outside through the anode exhaust port 60. Specifically, such oxygen gas is ionized in a reductive environment to the oxygen-depleted water area at the bottom, which causes the supply of nutrition to the blue-green algae. By being mixed in the aerated air, the growth of blue-green algae can be better suppressed, and the production of blue-green algae toxins and water-bloom offensive tastants can also be suppressed.

The cathode gas-liquid separation plate 113 and the anode gas-liquid separation plate 123 may be of a separate type or an integral type connected to each other, and can be designed as required.

[Fourth Embodiment]
Next, a fourth embodiment of the present application will be described with reference to FIG. In the structure of the water treatment apparatus according to the fourth embodiment, the description of the same structure as that of the water treatment apparatus according to the third embodiment will be omitted.

FIG. 6 is a structural schematic diagram of a water treatment device according to a fourth embodiment of the present application. A difference between the water treatment apparatus according to the fourth embodiment and the water treatment apparatus according to the third embodiment is that the separator 130 is provided between the cathode chamber 110 and the anode chamber 120 .

In the present application, the cathode chamber 110 and the anode chamber 120 in the electrolytic chamber 10 may or may not be connected. FIG. 6 shows an example in which a separator 130 is provided between the cathode chamber 110 and the anode chamber 120 in the electrolysis chamber 10. As shown in FIG. The separator 130 can exchange ions between the cathode chamber 110 and the anode chamber 120 . Note that the separator 130 may exchange only ions instead of water molecules between the cathode chamber 110 and the anode chamber 120 . Further, the separator 130 may be a water-permeable membrane that exchanges not only ions but also water molecules between the cathode chamber 110 and the anode chamber 120 .

Such a structure allows separate circulation systems to be formed in the cathode chamber 110 and the anode chamber 120 . This allows, on the one hand, to generate more alkaline electrolyzed water by electrolysis in the cathode chamber 110 to neutralize the low pH value at which phosphate ions are likely to be eluted in the bottom area of reservoirs, lakes or rivers. On the other hand, the hydrogen gas produced near the cathode 111 can be better recovered. Similarly, on the one hand, more acidic electrolyzed water can be generated by electrolysis in the anode chamber 120 to kill the blue-green algae, and on the other hand, the oxygen gas generated near the anode 121 can be better can be recovered.

In order to better explain the effects of the present application, the inventors of the present application used the water treatment apparatus according to the fourth embodiment of the present application to purify polluted rivers in Wenzhou, China.

First, a 500 mL beaker was filled with water from the polluted river in Wenzhou, and the apparatus was installed in the beaker. The equipment used was a Zhaoxin KPS-3005D charging device, with 3 cm square titanium electrodes as both electrodes, a distance between the electrodes set at 5 cm, and a 2 mm thick fibrous membrane in the middle of the electrodes. divided into wards. The overvoltage was 20 V and 0.14 A.

Next, at 25° C., the oxygen gas produced in this experiment was mixed into the aerated air, and the test results before and after mixing the oxygen gas produced in the above experiment were measured. In this experiment, the aeration rate is 1 L/min and the water rate is 10 L. Table 1 shows the oxygen content in water after 0 min, 5 min and 10 min of aeration, where the unit is mg/L.

In order to demonstrate the water-bloom suppressing effect of the technology of the present application, the acidic ionized water produced in the present application was added to the surface of the water at a flow rate of 1 mL/min for 30 minutes to 10 L of mixed water containing algae, green algae, and diatoms. Additions were made once daily. The ratio of each alga after 5 days was compared. At this time, the culture conditions for the blue-green algae, green algae, and diatoms were all 3000 Lux, 24 hours, and 20°C. Table 2 shows the test results.

As can be seen from Tables 1 and 2 above, the water treatment apparatus according to the present application can efficiently electrolyze the electrolyte components in the raw water to generate acidic electrolyzed water and alkaline electrolyzed water. Water can not only kill algal blooms without breaking the cell wall, but also effectively inhibit the growth of algal blooms. In addition, the water treatment apparatus can decompose water molecules into hydrogen gas and oxygen gas, the hydrogen gas can be recovered and used as fuel, and the oxygen gas can ionize phosphoric acid in a reducing environment. However, by being mixed in the aeration air to the bottom oxygen-depleted water area, which is the cause of supplying nutrients to the algae, it is possible to supply oxygen more efficiently than the conventional aeration technology, and the growth of the algae is better. can be suppressed to
